You are black. Once you were playing a good game and then, suddenly, you saw a nice piece of white territory. "Ha!" you said for yourself, "I will turn this territory into neutral points!" You made a perfect plan and started. But your opponent was smart and the territory turned to be a trap. Your stones got surrounded and cut from their friends on the left.
Once more, the game depends on your calm mind and ability to solve this uneasy position!
